March 24 Harry Houdini, magician and escape artist, was born in 1874. He was famous for being able to escape from extremely complicated and difficult traps. He once said, “My brain is the key that sets me free.” What do you think he meant by that?
March 28: The first Spanish settlement in San Francisco Bay was begun in 1776 by Juan Bautista de Anza. Suppose you were selecting people to set up a new colony in a far-away place. What skills do you think such colonists should have? List 10 skills, then decide whether each skill is necessary for every colonist, or is only needed by a few of them.
I am currently building a webiste for science teachers who are passionate about getting their students thinking about science. There are lots of free teaching resources to use in your classrooms as well as ideas specific to science pedagogy. Please check it out and let me know what you think.

I need help to know how to calculate how to calculate how many electrons in each shell of an atoms. And if it's different how to find out how many valence electrons.
Also, here is a good rule: The maximum number of electrons that can fit in any given shell is given by 2n². That's shell number squared times 2 ...Which would mean 2 electrons could fit in the first shell, 8 could fit in the second shell, 18 in the third shell, and 32 in the fourth shell.
Check out the resources at freesciencestuff.com and also sciocity.com . Lots of this stuff is geared to HS science and it might be of great value. John Davenport
